The Greek stock market is crashing. The Greek stock market reopened for the first time in five weeks, and it's ugly. The benchmark ASE index plummeted 22.8% before recovering some of its losses. Piraeus Bank and National Bank of Greece crashed the maximum 30% before being halted.

The Greek economy is crashing. Greece's economy screeched as political turmoil took over. The Markit manufacturing purchasing managers' index (PMI) reflected a record contraction, crashing to 30.2 in July from 46.9 in June. Any reading below 50 signals contraction. "Manufacturing output collapsed in July as the debt crisis came to a head," Markit's Phil Smith said. "Factories faced a record drop in new orders and were often unable to acquire the inputs they needed, particularly from abroad, as bank closures and capital restrictions badly hampered normal business activity. Demand was hit amid the heightened uncertainty surrounding Greece's future, leading both total new business and exports to contract sharply, and it remains to be seen how long it takes these to recover."

The rest of Europe is doing much better. The composite eurozone manufacturing PMI signaled growth, registering at 52.4 in July, which was higher than the earlier estimate of 52.2. Germany, Spain, and Italy all grew. "The eurozone manufacturing economy showed encouraging resilience in the face of the Greek debt crisis in July," Markit's Chris Williamson noted. "The PMI held close to its June level, which had been the highest for over a year, coming in ahead of the earlier flash estimate largely on the back of stronger than previously recorded growth in Germany."

HSBC beats. "HSBC Holdings beat expectations with a 10% rise in first-half profit thanks to a strong performance in Hong Kong and said it had agreed a $5.2 billion sale of its business in Brazil," Reuters reported. "Europe's biggest bank by market value is to sell the unprofitable Brazilian arm to Banco Bradesco SA, Brazil's second-biggest private-sector bank, for a higher than expected 17.6 billion reais ($5.2 billion)."

Puerto Rico will default. "Puerto Rico will miss a payment on debt due Aug. 1, the governor's chief of staff said on Friday, an event that will be considered a default by investors as the commonwealth lurches towards what could be one of the largest US municipal debt restructurings in history," Reuters reported. "The missed payment will mark the first default by the commonwealth and shows the depth of the island's economic and cashflow problems. Puerto Rico Governor Alejandro Garcia Padilla shocked investors in June when he said the island's debt, totaling $72 billion, was unpayable and required restructuring."

Bitcoin-exchange CEO arrested. "Mark Karpeles, the head of the collapsed MtGox Bitcoin exchange who was arrested in Tokyo, is facing fresh allegations that he misused $8.9 million in customers' deposits, Japanese media reported Sunday," AFP said.
